[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a snow stopper installed on a roof.

[0002]

[Prior art]

 As a snow stopper provided on the roof in order to prevent a sudden fall of snow, those shown in FIGS. 7 and 8 are generally known. In this snow stopper, a fixing piece B to the roof surface is stepped down and connected to one end of a supporting plate A formed in a strip shape with a stainless steel plate or the like, and an L-shaped snow is formed on the other end of the supporting plate A. The stopper C is formed upright.

As shown in FIG. 8, the snow stopper hooks the step-down part of the fixing piece B at a predetermined position on the upper end of the first step D1 of the roofing material such as a color vest laid near the eaves. , A fixing plate B is nailed to the roof surface, and a part of the supporting plate A out of the supporting plate A and the snow retaining piece C placed on the upper surface of the roofing member is covered with the lower surface of the second-stage roofing member D2. It is fixed by holding it down. As many snow stoppers as are fixed in this way are arranged in a staggered pattern of two or three steps on the entire roof.

[0004]

[Problems to be solved by the device]

 However, in the case of such a snow stopper, due to the weight of the snow received by the snow stopper piece C, a moment acts to bend the support plate A in an arc shape above the roof with the above-mentioned one end as a fulcrum, and the upper roofing material There is a problem that a force in the peeling direction acts on D2.

Further, if the plate thickness of the support plate A is increased in order to reduce the above-mentioned bending and prevent the roofing material from peeling off, the cost is increased.

In view of these problems of the conventional snow stopper, the present invention is a snow which can be manufactured at low cost without a strong force for peeling off the roofing material for fixing the snow stopper. It is intended to provide a stop.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention forms a snow stopper on the other end of a supporting member having a mounting portion fixed to the roof at one end, and attaches the mounting portion and the supporting member material. While sandwiching the part near the bottom with the upper surface of the lower roofing material and the lower surface of the upper roofing material, the above snow stopper and the portion of the supporting member near the snow stopper are placed on the upper surface of the lower roofing material. In the snow stopper to be exposed and mounted on the roof, the flexural rigidity of the non-exposed portion of the supporting member sandwiched by the roofing material is higher than the flexural rigidity of the exposed portion exposed on the upper surface of the roofing material. It is characterized by the fact that it is formed on the.

The difference in bending steelness between the exposed portion and the non-exposed portion of the support member is achieved by making both portions have a cross-sectional shape that causes a difference in their second moments of area. It may be achieved by using different materials.

[0009]

[Action]

 In this snow stopper, when the snow is piled up on the roof and a moment force in the direction of causing the snow stopper member to fall forward due to the weight of the snow acts, the exposed portion of the support member bends first and fully. Therefore, this moment force is consumed and the non-exposed portion of the support member is not bent, so that peeling of the roofing material is prevented.

[0010]

【Example】

 Hereinafter, the present invention will be described in detail based on illustrated embodiments. FIG. 1 shows a snow stopper according to an embodiment of the present invention. Reference numeral 1 in the figure is a support member having a snow stopper piece 4 attached to the front end thereof. The support member 1 is divided into two parts in the middle of the length direction, with the base end side as a fixing portion 2 and the front end side as a buffer portion 3. is there. The cushioning portion 3 forms a portion exposed from the roofing material when the snow stopper is attached to the roof, and the fixing portion 2 forms a non-exposed portion pressed against the roofing material and hidden from the roof surface.

The fixing portion 2 is made of, for example, a stainless steel strip plate material having a thickness of 0.8 mm and a width of about 10 mm, and two strip plate pieces 2b and 2b are parallel to each other from the rear end portion 2a having a substantially U shape in a plane. Extends to. A screw hole 2c is formed in the plate surface of the rear end portion 2a to form a mounting portion on the roof surface. Further, the two strips 2b, 2b are formed with steps corresponding to the thickness of a roofing material such as a color vest in the middle thereof.

The buffer portion 3 has a wire rod having a diameter of, for example, 0.8 mm, folded back in a substantially U-shape at its front portion 3 a, and its both ends have the front ends of the two strips 2 b, 2 b of the fixed portion 2. Is welded to. Comparing the magnitudes of the moments of inertia I2 and I3 of the cushioning portion 3 and the fixing portion 2, respectively, I2> I3, and assuming that the elastic coefficients of both portions 2 and 3 are equal to an acceptable level, the fixing portion Since the bending steel property (EI) of No. 2 becomes large, the cushioning portion 3 has a characteristic of being more easily bent than the fixing portion 2. In addition to the difference in the moment of inertia of area between the cushioning portion 3 and the fixed portion 2, as shown in FIG. 2, for example, the fixed portion 12 is formed in a flat plate shape, and the cushioning portion 13 is different from that of the above embodiment. It can also be achieved by forming a similar wire. In the figure, reference numeral 10 in the figure is a support member, and 14 is a snow stopper.

The snow retaining piece 4 attached to the front portion 3a of the buffer portion 3 is formed of a thin steel material or a synthetic resin material into a substantially U-shaped plane having a front plate 4a and both side plates 4b and 4b. The portion surrounded by the front plate 4a and the side plates 4b, 4b constitutes a snow receiving space. The snow retaining piece 4 has holder grooves 4c on the lower sides of both side plates 4b, 4b and the front plate 4a, and the U-shaped front portion 3a of the buffer 3 is fitted into the holder grooves 4c. To be done.

As shown in FIG. 3, the present snow stopper hooks the stepped portion of the fixing portion 2 on the upper end of the first-stage roofing material 5a, and drives a screw into the screw hole 2c at the rear end of the fixing portion. By fixing the upper surface of the fixed part, which is fixed to the roof surface and is in front of the step, with the second step roofing material 5b, the cushioning portion 3 and the snow stopper 4 are exposed on the upper surface of the first step roofing material 5a. It can be attached.

When snow is accumulated on the roof and starts to be stopped by the snow stopper pieces 4, the weight of the snow acts on the buffer portion 3 and the fixed portion 2 via the snow stopper pieces 4. However, since the bending rigidity of the buffer portion 3 is not equal to or smaller than that of the fixed portion 2, this moment force is consumed by bending the buffer portion 3 as shown by the broken line in FIG. Especially, the portion sandwiched by the first and second steps of roofing members 5a and 5b is not bent. Therefore, no force for peeling the roofing material 5b on the second stage acts, and the peeling phenomenon of the roofing material 5 is eliminated.

The fixing portion of the support member may have a flexural rigidity larger than that of the buffer portion at the portion sandwiched by the upper and lower roofing materials, and therefore, as shown in FIG. The mounting portion 22a may be formed of the same wire material as the buffer portion. The mounting portion 22a can be fixed with a screw by bending the rear end into a hook shape or partially forming a loop. Also, a structure may be adopted in which a thin plate material such as steel is covered and fixed to the roof surface by passing screws through screw holes provided on the plate surface.

FIG. 6 shows another embodiment of the present invention. In this embodiment, the exposed portion and the non-exposed portion of the support member 31 are formed of members having different elastic coefficients. The buffer portion 33 of the exposed portion to which the snow stopper 34 is attached is, for example, a rubber strip material having a thickness of 2 mm and a width of 10 mm, and the fixing portion 32 of the non-exposed portion is a hard member having the same thickness and width as the buffer portion 33. It is made of synthetic resin, stainless steel, etc., and both parts are joined by steps such as steps and polymerization.

Therefore, in this snow stopper, since the elastic modulus of the fixing portion 32 and the cushioning portion 33 are greatly different, a large difference is generated in the bending rigidity between the two, and the cushioning portion 33 is much more than the fixing portion 32. Easy to bend.

As described above, according to the present invention, a difference in bending rigidity may be generated between the exposed portion and the non-exposed portion of the support member even if the sectional shape is the same, depending on the selection of the material. Further, in the present invention, the mounting portion provided at the rear end of the support member, the snow retaining piece, and the mounting portion of the snow retaining piece at the front end of the supporting member do not matter in their structure.

[0020]

[Effect of the device]

 As described above, according to the present invention, the support member of the snow stopper having the roof mounting portion at one end and the snow stopper member at the other end is provided on the upper and lower portions of the exposed portion exposed on the upper surface of the roofing material. Since the bending rigidity of the former is smaller than the bending rigidity of the latter at the non-exposed part sandwiched by the roofing material, the moment force acting on the snow retaining member and the supporting member due to the weight of snow is exposed to the supporting member. This can be absorbed by the bending deformation of the portion, and the moment force is not applied to the non-exposed portion of the supporting member, and the peeling of the roofing material can be prevented.

Further, according to the present invention, it is possible to contribute to the manufacture of an inexpensive snow stopper by reducing the material cost.
